Brachytherapy, also known as sealed source radiotherapy or endocurietherapy, is a form of radiotherapy where a radioactive source is placed inside or next to the area requiring treatment. Brachytherapy is commonly used to treat localized prostate cancer, cervical cancer and cancers of the head and neck.

Breast brachytherapy is a 5-day radiation therapy alternative for women with early stage breast cancer.  External beam radiation therapy is safe and very effective, but can take over six weeks of daily treatment. Breast brachytherapy, or partial breast irradiation (PBI), has been researched and tested by Dr. Robert Kuske since 1991 as a treatment method after lumpectomy. He has advanced the techniques and technology, and championed the research bringing breast brachytherapy to where it is today. He has remained totally commited to his patients, who let him know in no uncertain terms that they wanted a shorter more convenient alternative with less radiation exposure to surrounding healthy tissues.
